Merge tag 'staging-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging / IIO driver updates from Greg KH:
 "Here is the big staging and IIO driver pull request for 5.11-rc1

  Lots of different things in here:

   - loads of driver updates

   - so many coding style cleanups

   - new IIO drivers

   - Android ION code is finally removed from the tree

   - wimax drivers are moved to staging on their way out of the kernel

  Nothing really exciting, just the constant grind of kernel development :)

  All have been in linux-next for a while with no reported issues"
